@Godfather: I'm aware of that workaround, but it doesn't work with the home- and misc tab. Remember, when accessing the ACP through the normal link, it links you to the HOME tab, but since it remains blank, no access is given to the rest of the ACP Thank you!

I am going to post here so that I can get a response as to when this might be fixed as mine is also not working.

The "temporary fix" only works for some tabs in the Admin panel. I cannot get to the Home or Misc tabs by going through the user profile to access the Admin panel. Those two tabs also take me to a blank page.

Sorry about starting a thread in "other problems" on this. Duh me. I didn't see this forum for Admin questions.

Edited to say that it now appears to be working again (as before). Thanks.
